Is O2 Homespot compatible with Smart DNS?

Before you change, u used DSL?

I think U need a public IP. With mobile connection you have CGN. U can get a public IP from o2. Price is 49,90€.

With a non public ip the smart dns is unable to identify U!

No. Static is always the same. Public IP is what you need for your smart dns.

The smart dns needs your „public ip“ to know that you are allowed to use the dns server.

So normally you tell the service i have IP xxx.xxx.xxx.xxx and you could use the dns.

With CGN you know only a private IP e.g. 10.xxx.xxx.xxx because you are sharing an IP with other users,

But the smart dns service get a request from the shared IP, so no access for you.

With public ip the ip U get is „you own“ IP and the dns service let pass you dns request.

So you have to tell you smart service every time (24h) the IP change the new IP address.

But that should be the same with a dsl connection.

Not really. I am unclear as to whether paying 50€ for a ‘public’ DNS address would solve the problem. I am also generally unimpressed with the connection speeds offered by the Homespot box and am actively exploring reverting to traditional router. I am awaiting a callback from O2.

Hi @Chrislan45,
​​​as @schluej explained, these are 2 different things. 
We can do it the same way: We set you the public IP, and if it doesn't work we change it again. There will be no costs for you. What do you think about it?

Kind regards

Hi @Chrislan45 ,
there is a one-time charge of 49.90 EUR for this. However, if the desired success does not occur within 14 days, we will take back the change and refund the 49.90 EUR. Please contact us for the setup and your agreement and also if the change does not work as expected.

Kind regards
Larissa

Hello @Chrislan45,

we don’t send confirmations by email. Is the assurance here in the public community not enough for you?

As you wrote, we will refund the charge if you are not satisfied with it. You can always contact us here for any complaints 🙂

Please let me know if you want the public IP to be activated or not.

Best regards

Giulia

Hello @Chrislan45,

I have activated the public IPv4 for your SIM card now. In order to use it, please change the APN from “internet” to “netpublic” in the settings of your home spot.

Please let us have your feedback if this has solved your issue.

Best regards

Hi Giulia. Unfortunately, switching to the public IP address has not solved the issue – I’m still having to manually reactivate the IP address every time i use the Smart DNS connection. Given that it isn’t working, please can you refund the setup fee? I’d also like to explore the option of upgrading my contract and reverting to a traditional DNS router. Please could you give me some guidance on how I might do this? Many thanks for your continued support.

Hello @Chrislan45,

the setup fee will not be invoiced, sorry this wasn't a solution for you.

As you have already contacted our customer service for the change to a DSL contract, is everything cleared already?

If you have further questions about this, please let us know.

Best regards

Giulia

The mail address is not suitable for support and contract processing! Your concerns are unlikely to be processed there. Please use fax or letter for important contract matters such as early termination.

For what its worth, I still haven’t received the new router even though the new contract was confirmed on 25 April. The technician came today and verified the phone connection but I can’t use the service because I don’t have a router. Also, the German customer service number is almost unfit for purpose. It’s virtually impossible to get past the virtual assistant. Seemingly endless unhelpful robotic loops end with “Would you like me to send you a confirmation email or SMS?”, then “Thank you, goodbye!” Why on earth is it so difficult to get to speak to a real person?
